About Angstroms
An angstrom (Å) is equal to 0.1 nanometers or 10⁻¹⁰ meters, named after Swedish physicist Anders Jonas Ångström. While not an official SI unit, it remains widely used in chemistry, solid-state physics, and crystallography to express atomic distances and wavelengths. A typical atom has a diameter of 1-3 angstroms, and the spacing between atoms in crystals is commonly measured in angstroms. X-ray crystallographers use angstroms to describe molecular structures with atomic precision.
About Fathoms
A fathom (ftm) is equal to 6 feet or 1.8288 meters, traditionally based on the span of a man's outstretched arms. This unit has been used for centuries in maritime navigation to measure water depth and rope or cable lengths. While largely replaced by meters in modern nautical charts, fathoms remain in use by sailors and in naval traditions. The Mariana Trench, Earth's deepest point, reaches about 6,000 fathoms. The term 'to fathom' meaning 'to understand' derives from this nautical unit.
